245/40/18 also fits fine without rub on 18" x 9" ET 30, although I can't say without camber. That's what I'm running right out on my spare set of OE rears up front at -3º camber. Tires are stretched enough where if I were to drop the tire with wheels on a flat ground, it would contact the rim. 255 would be a better size to run to afford some minor protection to the rim.
Say hi to Eddie for me, I had dinner with him and Patrick about a month ago at Buttonwillow.

Hack - what tires are you running? Surprised to hear that 245 is slightly stretched on a 9”...
Do you think there’s any adverse effects on handling by running mismatched diameters, e.g. taller tires in rear by +0.3” relative to fronts?
